IMPROVEMENT IN TUCKING DEVICES FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 123,529, dated February6, 1872.

I, J OHN W. WHARTON, of Bourneville, Ross county, Ohio, havejnvented anew and useful Tucker Attachment for Sewing-Machines, of which thefollowing is a specification:

This is an improved device for guiding or conducting the cloth to theneedlesin proper-- ly-folded condition for any desired tuck, whetherbroad or narrow, and at any desired distance between the consecutivetucks.

In the accompanying drawing, Figure 1 is aperspective view of a tuckerembodying my invention. Fig. 2 is avert-ical section thereof. Fig. 3 isa plan of the same, a portion of the loop being omitted. Fig. is anenlarged section of the operative parts.

A is aflat bar or plate of spring-steel, bent over and backward so as toform a loop, B, and yielding tongue 0. In the under side of the bar A isa dovetailed groove,a, to receive and hold, by means of screw D, theslotted arm E of ab *acket whose portion F is also slotted to receivethe screw G, by which the tucker is attached to the cloth-plate.Interposed between the two parts A and O of the bar A B O is my spacer,which is aflat slotted bar, H, slidable along and parallel with the barsA between guides I, and secured to any desired adjustment on said bar Aby screw J, which traverses slot h in the said bar A. The eiiective endof the spacer terminates in a lip, It, and shoulder It, which shoulder,in use, is always brought into close contact with the back of the lasttuck. By adjusting the said spacer to the right or left along the bar A,the seamstress is enabled to regulate the distance from tuck to tuck.Pivoted to the bar A by means of screw L is a plate, M, having guides onfor my tuck, plate 0 of which is, by means of screw P and slot 0, sosecured to the plate M as to give the desired width of tuck. The

distance from tuck to tuck, and the width of tuck are regulated,respectively, by the distance of the ends h and 0 of the spacer andtucker from the end 0 of the bar A B O. A stop, Q, in the bar A B O,limits the deflection of the tuck-plate O, and, being applied to theedge of the said bar nearest to the needie, the progress of the workitself operates to hold the said tuck-plate in position. The side of thebar to which said stop is to be applied will depend upon the kind ofsewingmachine to which the tucker is attached. A scale of-sixteenths ofan inch upon the upper surface of the portion 0 serves the doublepurpose of accurately regulating the width of the tucks and theirdistance from each other.

'The operation is as follows: The parts being secured in properposition, as above explained, the presser-foot is raised and thetuckplate swung backward, as in Fig. 3. The material to be tucked isthen inserted in the loop B, and its edge drawn under the portion 0until the back of the previous tuck presses against the shoulder IL" ofthe spacer H. The cloth is then folded forward over the portion 0, andthe tuck-plate O is brought to its position over the part thus folded.The cloth is then finally folded backward over the tuckplate, the foldadjusted under the presser-foot, and the stitching proceeded with. Theposition of the cloth with relation to the operative parts is indicatedby dotted lines in Fig. 4.

Claim.

I claim herein as new and of my invention- The described arrangement ofbent and yielding bar A B 0, adjustable spacer H, pivoted plate M,adjustable tuck-plate O, and slotted arm E F, the whole being combinedand adapted to operate in the manner set forth.

In testimony of which invention I hereunto set my hand.
